"Lomasa said, 'O son of Kunti! one who visits the sapphire Hill and plunges his body in the river Narmada attains the regions inhabited by the celestials and kings. O most praiseworthy of men! this period is the junction between the Treta and the Kali age, O Kunti's son! This is the period when a person gets rid of all his sins. O respected sir! this is the spot where Saryati performed sacrificial rites, wherein Indra appeared in a visible form and drank the Soma juice, with the two celestial physicians. And Bhrigu's son of severe austerities conceived anger towards the great Indra; and the mighty Chyavana paralysed Indra, and for his wife obtained the princess, Sukanya.'"
